OPEN FIRE-PLACE.

SPECIFICATION forming part of Letters Patent No. 241,496, dated May 1'7, 1881.

' Appiimion inea March 2, 1881. (No model.)

To all whom @t may concern:

i of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the aecompanyin g drawings, which form a part of this specification.

Figure l is a vertical sectional view. Fig. 2 is a rear view, part of the hot-air conductor being broken away to show the construction; and Fig. 3 is a section on line w x, Fig. 2.

Similar letters of reference indicate corresponding parts in both figures.

This invention relates to that class of open grates or heaters which are provided with a double back or easing forthe passage of a current of air, which is thus heated land conducted to an apartment on the upper floor, where it may be discharged through a register; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described with reference to the drawings, in whichp,

A A represent the brick wall, and B the chimney. t,

C represents the tire-place, D the ornamental mantel, and E the fire basket or grate, which is provided with hooks F, by which it is hung and supported upon sui tably-arran ged studs G upon the sides of the iire-place.

H is a double casting or casing, adjusted at the rear end of the fire-place and forming the back and top of the latter.

I I are transverse plates, arranged horizontallyin the rear or vertical section of the casthe casing, to ascend in a zigzag course. The upper or horizontal portion of easing H is provided with avertical U-shaped partition, K, serving to divide the current of air, as indicated by the arrows, before reaching the centrally-located flue or opening L conducting upwardthrough the chimney to the register 1ocated in an upper apartlnent, which may in this manner be heated.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of our invention will be readily understood. It is simple, inexpensive, eff'ective in heating the upper apartment as well as the room in which the grate is lo cated, and easily applied in hre-places of the ordinary construction.

We are aware that it is quite common in hotair lire-places to provide the conducting-fines with horizontal plates to insure a zigzag course of the hot-air current; but we are not aware that the herein-described arrangement of the horizontal plates I, in combination with the U- shaped vertical plate K, has been ever before known or used.

AHaving thus described our invention, we

claim and desire to secure by Letters Patent of the United States- The combination, with an open lire-place, of the double casing H, having opening J, horizontal plates I, and vertical U-shaped partition K, and the flue L, all arranged and oper-
